The lower blade 4 may then be turned on the pivot 8 to a position atright angles to the upper blade, and locked in that position by movingthe latch 6 into the notches 5. The blades are then raised and the heelend 3 of the blade 4 may then be slipped over the stud 2 and loweredthereon and may be'retained there as by a nut 2a threaded onto the endof the stud. A lock nut may also be employed to secure the nut 2a,especially in case the blade is to be rotated in an anti-clockwisedirection. These nuts may readily be supplied to the stud as by anelongated socket wrench inserted through the bunghole.

paint or other. material for shipment. To remove the blade, I unscrewthe nut, 2a, where--v upon the blade may be lifted from the bottom ofthe barrel and to a point adjacent to the bun'g-.

hole and the latch may be disengaged from the locking position and theblade 4 swung downwardly, and the blade easily removed from the barrelso that the barrel may be cleansed. It .will be seen that when the bladeis secured in operating position by the locking latch that the stirringoperation may be I performed without an upward movement of thehorizontal blade and that the latch effectively holds the horizontalblade in any desiredposition relative .to the bottom of the barrel. Iprefer to cut the notches 5 at such an angle and in such relation to thepivot 8 that the blade 4, when locked in position, will sweep closely tothe bottom of the barrel but not in contact therewith. Thus the materialwhich tends to adhere or collect in the lower corner of the barrel iselfectively agitated and removed therefrom by the rotation of thestirrer blade.

I prefer to effect the rotation of the blade by means of a crank handle9 of the form shown. The stirrer engaging portion of the handle is soformed as to be heldvfirmly in operation by the walls of the bungholeand is slotted to receive the upper end of the blade '7 as at 11. It isusual to form the bunghole with a flanged threaded sleeve member asshown which may be securely welded or otherwise secured to the'top ofthe barrel. The threaded member is adapted to receive the useful screwcap having a hexagonal head. When the cap is unscrewed and the handleinserted the threaded'sleeve may act as a journal member preventinglateral movement of the engaging portion of the handle. I provide a lip'or projection 10 at the end of the handle which is adapted to engagewith the inner surface of the head adjacent to the edge of the bunghole.Adjacent to the lip portion, the handle is notched to receive the upperend of the stirrer blade 11, the outer portions ofthelegs of the notch12 and 13 being dimensioned to fit snugly within the bunghole 14. Iprefer to extend the stirrer bar up flush with the top of the bungholeand to construct it of material suificiently rigid to resist itsdisplacement downwardly by the handle thus insuring a close contact ofthe stirrer bar within the notch. s Iclaim: e

1. A stirring device adapted to be secured to the center of the bottomof a container having a bunghole at the opposite end thereof,-said stir-,rer comprising two flat blades, the lower -blade beingpivotallysecuredat its outerend 'to the upper blade, the upper bladebeing twisted helicoidally upwards to the topof the bunghole, and meansfor locking said blades in right angle relation foroperation,'saidlockingj'means being The barrel or drum is then ready tobe filled with engagedin operation. 1

I

5. In combination, a barrel having a bunghole, an articulated stirringdevice'insertible and removable through said bunghole, said stirringdevice comprising a pair of blades pivotally connected, one bladeextending'horizontally adjacent to the bottom of the'barrel and nearlyto the wall thereof, the other blade extending vertically adjacent tothe side of the barrel for approximately half its length,'then towardsaid bunghole,

and releasable meansfor locking said blades in substantially right anglepositions.

6. In combination with a barrel having a central bunghole sleeve, anarticulated stirring device insertible and removablethrough said bunghole, comprising two blades, the lower blade being pivoted at the bottomof said barrel, theupper blade being pivotally attached, to the lowerblade at the outer end thereof and provided with releasable means forlocking said blades in substantially right angle relation, the upperblade extending upwardly along the side of the barrel .and toward thebunghole, a crank handle having .a portion adapted to engagethe innerend of the sleeve to prevent'the handle from becoming dis- 7. Incombination, .a container having. a central bunghole at the top thereof,a stirring device composed of twoblades pivotally joined together, oneblade being adapted for support adjacent to the bottom of saidcontainerand pivoted at the center of said container at the bottom thereof, saidblade being provided with notches at the upper outer edge, the otherbladeextending upwardlyadjacentthe side of said container, and benttoward the bunghole, ,and with latching means at the lower end tocooperate with'the notchesof the lower blade to support said lower bladeat substantially right angle relation, said stirring device beingjournaled. within the bunghole, a crank handle adapted to rotate saidblades, having means to prevent said blades from rising out of thebunghole in operation.

8. In combination, a container having a bunghole with a surrounding rim,a stirring blade having a rectangular flat upper end portion extendinginto said bunghole, a crank handle, said handle in operating positionbeing provided at its outer end with an upwardly extending handle, anarm portion, an axis portion loosely revoluble within the bungholewithin which it is to be rotated, said axis portion being provided witha slot adapted to receive and engage the end portion of said blade andhaving a horizontally extending lug opposite said arm portion adapted toloosely fit beneath the rim of the bunghole and be held down thereby.

9. In combination with a barrel having a bunghole, an articulatedstirring device vtherein, said device being insertable and removablethrough said bunghole and comprising a pair of pivotally connectedmembers, one member being horizontally adjacent to the bottom of thebarrel, the other member having a lower portion disposed substantiallyvertically adjacent to the side of the barrel and an upper portionextending to the said bunghole and means for locking said members insubstantially right angle relation.
